Explain to me why technology has developed a non-adjustable stem? That just seems like nonsense to me. Even if you own the bike for 20 years, you're going to want to adjust it up or down. Even in my first season riding again I was ready to adjust it down a little, and I sure know it's inches higher than it was than when I was in my 20's.

The answer has to be more than "to sell more stems", because, well, I'm a believer in free enterprise and capitalism!
